The sorption ability of textile fibres

The paper deals with the sorption capacity of textiles fibres for surfactants and water. Adsorption of surfactants was characterized through adsorption isotherms, adsorbed, desorbed and residual amount of ionic surfactants in variation of hydrophilic and hydrophobic part and concentration as well. Water sorption was expressed as moisture content and water retention value of textile fibres. Cationic and anionic surfactants were adsorbed on the cotton, wool, polyester and polypropylene fibres at 20°C during 60 minutes. Desorption of surfactants was performed at 20°C during 30 minutes. The results obtained indicate that the key parameters in adsorption process are concentration and composition of the surfactants, as well as the swelling capacity of textile fibres.
